Full solution

Q. Shaniece owns a small business selling bagels. She knows that in the last week

83

customers paid cash,

7

customers used a debit card, and

21

customers used a credit card.

\newline

If next week, she is expecting

1600

customers, about how many would you expect to pay with a credit card? Round your answer to the nearest whole number.

\newline

Answer:

Calculate total customers: Calculate the total number of customers from last week. $\newline$ Customers who paid cash: $83$ $\newline$ Customers who used a debit card: $7$ $\newline$ Customers who used a credit card: $21$ $\newline$ Total number of customers last week = $83 + 7 + 21$ $\newline$ Total number of customers last week = $111$
Calculate credit card proportion: Calculate the proportion of customers who paid with a credit card last week. $\newline$ Proportion of credit card payments $=$ Number of customers who used a credit card $/$ Total number of customers $\newline$ Proportion of credit card payments $=$ $21 / 111$
Calculate expected credit card customers: Calculate the expected number of customers who will pay with a credit card next week. $\newline$ Expected number of credit card payments $= \text{Proportion of credit card payments} \times \text{Total expected customers next week}$ $\newline$ Expected number of credit card payments $= \left(\frac{21}{111}\right) \times 1600$
Perform calculation for expected customers: Perform the calculation to find the expected number of credit card payments. $\newline$ Expected number of credit card payments = $(21 / 111) \times 1600$ $\newline$ Expected number of credit card payments $\approx 0.1891891891891892 \times 1600$ $\newline$ Expected number of credit card payments $\approx 302.7027027027027$
Round expected credit card payments: Round the expected number of credit card payments to the nearest whole number. $\newline$ Rounded expected number of credit card payments $\approx 303$
